I've had this GPU (GTX 660 ti) for about a year and a half now. I haven't had any problems with it until recently (maybe like a week). Whenever I play games like Starcraft 2, Age of Wonders 3, and right now Archeage, there are very visible problems happening. It's kind of hard to explain, but I'll do my best.
I looked for images of screen tearing, because that's what I thought it was at first, but none of the images that I was finding looked like my issue. Really the best way I can explain it is that there are lines/boxes of messed up graphics that go to the center of my screen and taper off into a point. If you could imagine this painting but in a game, It's what it looks like as far as that they all go to the center of my screen, but not to a specific point like in that link. Those lines/boxes don't stay in a single spot either, they go all over the place and flicker. I should also mention that not all of (whatever you would call this problem) it goes to the center of my screen; it really goes all over, but the majority does go to the center of my screen.
It seems to be messing up on effects, for instance, I was fighting a boss on Starcraft 2 and he was spitting out these pools of acid on the ground. I wasn't having much of a problem until those starting getting thrown out and my graphics were really messing up. There was another instance of my issue on another game, Age of Wonders 3, and it was a pretty similar situation. An AI cast some spell on a city and it was something that stayed on that city until I dispelled it. I still experienced my issue whenever I wasn't looking at my city but when I would my issue would get worse.
Again, I wish I could get some picture to show you guys, but it's really hard to take a screen shot because it's flickers all over the place and doesn't stay in a single spot.
